fix(serena): stop the memory restating a budget it does not own, and gate the surface it lived on - #566
Conversation
CLOUD-769 `mem:serena-setup` still prescribes the retracted 30,000 ms budget, and tells a diagnosing reader to expect the failure signature as the healthy one
Why CLOUD-668 → CLOUD-700 → CLOUD-730 retracted the 30,000 ms MCP startup budget and replaced it with a measured 120,000 declared in CLOUD-730's own Provenance block says it chased that number across every surface carrying it: "They had reached CLOUD-668, CLOUD-700 and (now) PR #504's body; the shipped gate header was the surface nobody checked, and it is the one a future maintainer reads first."
1. A prescription derived from the dead number, for a gate that exists and does the opposite.
Both halves are now false. The declared budget is 120,000, and the gate this sentence specifies was built by CLOUD-700 — it asserts the observed budget read from the client's own connection log, not a derived effective figure. A reader following this sentence would build the gate that already exists, to the wrong specification. 2. The worse one: the diagnostic instruction names the failure signature as the thing to look for.
A 3. The file already knows the right form and broke its own convention here. The same memory writes the pinned version as Two further corrections, measured while establishing the above. Both are pointer-shaped facts with no owned value in them, and both are traps in a log this memory sends the reader to first:
Not in scope, stated rather than left to inference. The dated measurements at lines 164-166 ( Also out of scope, filed separately: that no gate reads Refinement — Ready (replace the restated budget with a pointer to the mechanism that owns it) Refinement gate: Definition of Ready & Done. This body carries only specializations.
Provenance. Found by measuring whether Serena was healthy. It is — 21 tools attached, LSP resolving cross-file references, memory graph clean, every Serena-related gate green. The health check passed; the memory describing it did not. CLOUD-770 No gate reads `.serena/memories/**` for restated values: the repo built that predicate twice, and both copies stop at the smaller prose surface
Why The repo has decided twice that prose restating a value a mechanism owns is a defect, and built a gate for it both times:
Measured population, across all 17 tracked prose surfaces. Seven mechanism-owned values are named in prose. The discipline mostly holds — six use the pointer form, naming the knob without quoting it, which is exactly what
Eight restatements, four files, three owning mechanisms, one gated. All currently agree, which is the point: this is the state Widening the glob alone does nothing. CORRECTED 2026-08-20, before implementing. This section originally gave a second reason: that And the same run corrects the population. Only one line in the whole tree matches the inverse syntax — So the syntax axis is dropped: it would gate exactly one value, which is the one-instance gate this issue's own "Rejected alternative" refuses. What survives is two moves that do not conflict:
Explicitly out of scope, and the reason matters. Matching a bare number with no adjacent backticked owner — the shape of A third shape, found while landing CLOUD-769, and it sharpens the out-of-scope line above. Correcting the memory, the first draft quoted the retracted sentence in order to mark it retracted — "this paragraph used to say the gate must expect ~28.3 s" — which is the pattern The distinction the pattern turns on is who owns the value, not how the sentence is framed: the gate file may quote its own retracted number, because it is the authority and the number is already there in force. A memory quoting the same number is a second authority whether the verb is "is" or "used to be" — a later reader greps, finds it, and cannot tell a retraction from a claim. So a retraction in prose names the issue that carries the record ( This is a drafting rule, not a new predicate: it is why the bare-number shape stays out of scope above rather than an argument for pulling it in. A gate matching bare numbers would flag the authority file's own retraction quote — correct prose in the one place the value belongs. Rejected alternative: a gate for the MCP budget specifically. It would be a gate over one value, and after CLOUD-769 that value is not in any prose surface to check. A gate for the category is worth building; a gate for one instance is test coverage with no population. Refinement — Ready (widen Refinement gate: Definition of Ready & Done. This body carries only specializations.
Provenance. Found by asking whether CLOUD-769's defect generalised, rather than assuming it did. The measurement is what says it does — and the same measurement is what rules out the one-value gate. CLOUD-774 `filed-over-own-diff` measures the overlap once at write time, so filing before you touch the file — the order AGENTS.md prescribes — buys a permanent zero
Why CLOUD-514 shipped It measures the wrong instant. Measured on a live session, 2026-08-20. Two rows filed before a single file had been edited, then the work done on the same branch: CLOUD-770 was the punt — filed and left in Backlog while the session landed something else — and it recorded The order that defeats it is the order the repo prescribes. AGENTS.md: claim it by hand, before writing code. A session that follows that instruction files while its diff is empty, every time. So the compliant sequence and the evasion sequence are the same sequence, which is why this is a defect in the mechanism rather than a discipline problem.
Second defect, and it is the one that costs money. The gate runs inside Verified before proposing, with a scratchpad prototype and no repo edits:
The exemption is not optional — without it the change inverts the gate. Recomputing at check time fires on rows the branch filed and then fixed, because their paths are in the diff by construction. Prototype against the real diff: Without the closing-key exemption every honest file-then-fix needs A collision to handle rather than discover later. Refinement — Ready (measure the overlap when it is asked, not when the row is written; exempt rows the PR closes; nudge at Stop) Refinement gate: Definition of Ready & Done. This body carries only specializations.
Provenance. The punt this describes was mine, twice in one session, and the second time the analysis of it was delivered instead of the fix. |

…inert The closing-key exemption landed in the gate and nowhere else. `land` still called `mise run filed-here-check` with nothing on stdin, so the gate found no closing keys and refused every row this branch filed and then fixed -- their paths are in the diff by construction. Caught by the first real landing after the change: it stopped on CLOUD-769 and CLOUD-774, both of which PR #566 closes. That is exactly the false positive the exemption exists to prevent, reintroduced by teaching a gate to read a surface and leaving the call site alone. Same shape as the hk glob earlier on this branch: a gate wired to a surface nothing routes to it. `$body` is already in hand from the deferral stop a few lines above, so this is the one line it always should have been. An empty body -- the fetch failed -- yields no exemption, which is the pre-change behaviour and refuses rather than waves through. Proven by a test rather than by assertion: the `mise` stub captures what `filed-here-check` receives on stdin, and the case asserts the closing key arrives. The stub records stdin before consulting the scripted exit code, so failing the gate stops the lap immediately and still proves what the call site handed over -- letting `land` run on would poll CI and never return. The stub is written through an UNQUOTED heredoc, so the comment documenting all this carries no backticks: a backticked word there is command substitution, and the first draft would have tried to execute the task it named. shfmt caught it.

… restating it `mem:serena-setup` still carried the 30,000 ms MCP startup budget that CLOUD-668 -> CLOUD-700 -> CLOUD-730 retracted. CLOUD-730's provenance records chasing that number across CLOUD-668, CLOUD-700, PR #504 and the gate header; this memory was the surface it missed, and it is the one a session reads when it is diagnosing exactly the failure the number governs. Two passages were wrong in different ways. The first derived a prescription from the dead value -- "a gate asserting the effective budget must expect ~28.3 s" -- for a gate CLOUD-700 has since built to the opposite specification, asserting the observed budget from the client's own log. The second told a reader to look for `timeout of 30000ms`, which is now the CLOUD-700 symptom rather than the healthy reading; measured on this container, both recorded connections opened at the declared value and a reader following that line would have called the healthy log anomalous. Neither is re-synced. The value is removed and the owner named: `MCP_TIMEOUT` in `.claude/settings.json` declares it, `mise run mcp-timeout-budget` judges it and carries the floor with its measurement. That is the form this same file already uses for the pin (`pipx:serena-agent@<v>`), which is why the pin reference never drifted while the budget did. Adds two diagnostic traps measured while establishing the above, both pointer-shaped: the handshake's `serverVersion` comes from the `mcp` SDK rather than Serena and reads as pin drift, and a slow attach is usually CLOUD-670's cold rust-analyzer index. Leaves CLOUD-714's dated measurements alone -- those are facts about the world at a date, not a value a mechanism owns, and that distinction is the point of the change. Refs: CLOUD-769
…t cannot match `rules-drift` (CLOUD-506) gates "a value prose restates still agrees with the mechanism that owns it" over `.claude/rules/*.md`. `.serena/memories/**` is the larger prose surface -- twelve memories read by the same agent, under the same "acts without re-deriving" premise -- and was subject to neither this predicate nor `perf-assert`'s. `memories-check` gates the graph's edges (CLOUD-183) and deliberately not content, so a restated value landing in a memory was judged by nothing. Adds `RULES_DRIFT_MEMORIES` to the walk. It catches nothing on the tree as it stands and the header says so rather than implying otherwise: the coverage is prospective, and it is worth one pathspec because the next `VAR (N)` or unwired `runs on` to land there is now caught on arrival. An absent memories root is not a failure the way an absent rules directory is -- a consumer repo without one is ordinary. The syntax axis this was refined with is dropped. Measured before implementing: exactly one line in the tree uses the inverse `N units (VAR)` form, so an arm for it would gate a single value -- the one-instance gate the issue's own rejected alternative refuses. The six restatements are converted to pointers instead, which is CLOUD-769's remedy: `board-states.md` names RELEASE_QUIET_MINUTES and RELEASE_MAX_WAIT_HOURS without quoting their windows, and the five `100ms` sites across `core.md`, `prior-art-and-issue-hygiene.md` and `toolchain.md` now point at `perf-assert`'s BUDGETS table, which already holds README's published column against it. Two bats cases exist because reasoning got this wrong once. The issue body asserted that a `<root>/*.md` pathspec does not recurse and that `workflow/` memories were therefore never read; git pathspec `*` crosses `/` and they were. The subdirectory case makes the walk's depth a fact rather than a belief about fnmatch, and the absent-tree case pins the asymmetry. Refs: CLOUD-770
The gate walks `.serena/memories/**` as of the previous commit, but the hk step listed only `.claude/rules/*.md`, `.claude/settings.json` and `mise-tasks/**`. A commit touching nothing but a memory therefore never ran it: the widening held in `verify` and `ci` while the pre-commit tier stayed blind to the surface the widening was for. Refs: CLOUD-770
… row is filed `filed-over-own-diff` (CLOUD-514) prices the punt: a row naming paths the branch is also changing is a defect you were holding the file for, so filing it is cheaper than fixing it. It measured the wrong instant. `board-write-record` computed the intersection once, at creation, and `filed-here-check` read that frozen number -- so the verdict described the diff at FILING time, not the diff that is landing. Rows are filed before any file is touched, because AGENTS.md says to claim by hand before writing code. The compliant order and the evasion order are the same order, and it recorded 0 every time. Measured 2026-08-20 on the branch that prompted this: CLOUD-770 filed with an empty diff recorded `0` and kept it, while the identical row groomed after an edit recorded a real overlap. The gate saw the second and could never see the first. The column now holds the paths a row NAMES -- a fact that does not decay -- and `filed-here-check` intersects it with `git diff --name-only origin/main...HEAD` when it is asked. `board-diff-overlap` gains `--named`, which is the existing computation printed one line earlier; it needs only `git ls-files`, so a container with no `origin/main` records the row instead of losing it to `-`. ROWS THE PR CLOSES ARE EXEMPT, and without that this change would invert the gate. Recomputing against the landing diff fires on a row the branch filed AND THEN FIXED, whose paths are in the diff by construction -- so every honest file-then-fix would need the override, and the cheapest way to dodge the refusal would become not filing the row at all. That is the property the board exists for in a container that can be reclaimed at any moment. `closing-key-check` gains `--list` and is CALLED rather than copied: it owns `$CLOSING_VERBS`, and a second copy of that regex would be one value in two files with no gate holding them equal -- the defect this whole change is about, which makes duplicating it here self-refuting. Also passes all three relation directions into the recorder's lint payload. `ready-lint`'s `deferral-cited-without-relation` accepts any direction, and its header says why: demanding `blockedBy` "would push authors to declare false dependencies to pass a lint". Synthesising only `blockedBy` reintroduced that pressure from the other side -- measured, CLOUD-769 recorded `unready` through four grooms for this and nothing else. Two `#MUTANT` rows are re-aimed. `overlap-ignores-the-diff` mutated to `sorted(named)`, which is now a legitimate mode rather than a defect -- the mutation and the feature had become the same bytes -- so it forces the named set in the DEFAULT path instead. A new `overlap-frozen-at-write-time` row drops `--named`, which only a case that files with an empty diff can catch. Six overlap cases in the suite asserted on the recorded number; they now create a real diff, so they test the predicate rather than a field. Refs: CLOUD-774
`filed-here-check` decides inside `land`, which is the most expensive moment available: after `verify`, with a runner about to be spent. The detection itself is a `git diff --name-only` and a set intersection -- measured on this container at ~13ms, against ~44ms of path resolution already paid once at write time -- so there is no reason it waits for the expensive step. Adds `--advisory`: the same predicate, the same pointer-only output, exit 0 always. One implementation rather than two, because a second copy of the intersection would be a second thing to drift. `stop-guard` runs it as a third rule, LAST. This file ranks its rules by measured precision -- `hedged-flag-framing` leads at 3/3 against `finding-sink-check`'s 1/1 -- and this rule has no measurement, so it takes the bottom slot rather than the top one its author would prefer. It emits through `additionalContext` and never exit 2, so nothing on the commit or push path can be blocked: pushing to a draft is what survives a container reclaim and must stay free. ONCE PER ROW PER BRANCH. A Stop hook sees no PR body, so it cannot tell a punt from a row this branch is landing the fix for -- and repeating one pointer every turn for a whole session is how "two nudges on one turn is how a channel stops being read" plays out over time. The turn an overlap first appears is the one that can still act cheaply, which is the point of moving this ahead of `land`. `land` is unaffected: the gate there reads the PR body and does not consult the record. The suite's silence assertions run inside this checkout, where a punt row filed by the session running them would make every one flap, so the fixture turns the rule off through the gate's own bypass and the cases that are about it run against a throwaway repo instead. Refs: CLOUD-774
The board-writes receipt is keyed by branch name and survives `git checkout -B <branch> origin/main`, the documented restart after a merge. Rows filed for a landed PR would then be intersected against an unrelated diff and refuse the next piece of work on that name. The base-sha scoping this was specified with does not work, and it was tested rather than assumed. After a merge the old base is STILL an ancestor of HEAD, so "not an ancestor" cannot see a reset; and "equals the current base" excludes rows filed before any ordinary rebase, which happens on every lap. Neither predicate separates a reset from a rebase. A merge does separate them, and it is an event rather than an inference. `land` already deletes the branch on the merged path; it drops `board-writes.<branch>` and `filed-here-nudged.<branch>` in the same place. By then every row the branch filed is landed, closed by the PR body, or recorded in the override log. Same posture as the branch delete beside it: a failure is silent, because the landing has already succeeded. Refs: CLOUD-774
`mise run mutant` refused three of the rows this branch touched with
`names-no-case`: the description is used as a bats `--filter`, and all three named
prose that matched no test. A mutation row pointing at a case that does not exist
proves nothing while reading exactly like coverage, which is the vacuity the
anti-vacuity term exists to catch. Found by running it rather than by review.
Each now filters to the case that discriminates it:
overlap-never-measured a row whose body names a changed file records a
non-zero overlap
overlap-frozen-at-write-time A FILE THIS BRANCH HAS NOT TOUCHED IS STILL
RECORDED
overlap-ignores-the-diff the default mode still intersects, so the same
body reports nothing
The last pairing is the load-bearing one: that case fails precisely when the
default mode stops intersecting, which is what the re-aimed mutation forces.

Use an unambiguous encoding for recorded paths.
Line 312 splits named paths on commas. Git permits commas in tracked filenames. A receipt for a/foo,bar.rs becomes two paths, so the current-diff intersection misses the actual changed file and the filing gate passes.
Replace the comma-delimited receipt format with an unambiguous encoding across mise-tasks/board-diff-overlap, mise-tasks/board-write-record, and this reader. Add coverage for comma-containing paths.

Iterate over files line by line
The loops at lines 103 and 130 use for f in $files. This performs word splitting and pathname expansion, so paths containing spaces or glob characters are not processed correctly. Use IFS= read -r and quote each path.

Do not consume a pointer when receipt persistence fails.
Line 149 ignores an append failure, but Lines 147-154 still emit the pointer. The consumed key is then absent from the receipt, so every later Stop hook reports the same row again.
Handle persistence failure before adding the line to fresh. If persistence fails, leave reason unchanged as this rule specifies.

Closes CLOUD-769
Closes CLOUD-770
Closes CLOUD-774
Found by measuring whether Serena was healthy. It is — 21 tools attached, LSP resolving cross-file references, memory graph clean, every Serena-related gate green. The health check passed and the memory describing it did not.
CLOUD-769 — the memory carried a value it does not own
mem:serena-setupstill prescribed the 30,000 ms MCP startup budget that CLOUD-668 → CLOUD-700 → CLOUD-730 retracted. CLOUD-730's provenance records chasing that number across CLOUD-668, CLOUD-700, PR #504 and the gate header; this memory was the fourth surface, and it is the one a session reads when diagnosing the failure the number governs.Two passages, wrong in different ways:
timeout of 30000ms, which is now the CLOUD-700 symptom rather than the healthy reading. Measured on this container, both recorded connections opened at the declared value, so a reader following that line would have called the healthy log anomalous.Neither is re-synced. The value is removed and the owner named:
MCP_TIMEOUTin.claude/settings.jsondeclares it,mise run mcp-timeout-budgetjudges it. That is the form the same file already used for the pin (pipx:serena-agent@<v>) — which is why the pin reference never drifted while the budget did.Also adds two diagnostic traps measured while establishing the above, both pointer-shaped: the handshake's
serverVersioncomes from themcpSDK rather than Serena and reads as pin drift, and a slow attach is usually CLOUD-670's cold rust-analyzer index.CLOUD-770 — nothing gated the surface that value lived on
rules-drift(CLOUD-506) gates "a value prose restates still agrees with the mechanism that owns it" over.claude/rules/*.md.perf-assertdoes the same for README's budget column..serena/memories/**is the larger prose surface — twelve memories read by the same agent, under the same "acts without re-deriving" premise — and was subject to neither.memories-checkgates the graph's edges (CLOUD-183) and deliberately not content.The gate now walks it, and the hk step's glob was widened to match, without which a memory-only commit never fired it — the widening would have held in
verifyandciwhile the pre-commit tier stayed blind to the surface it was added for.The syntax axis this was refined with is dropped. Measured before implementing: exactly one line in the tree uses the inverse
N units (VAR)form, so an arm for it would gate a single value — the one-instance gate the issue's own rejected alternative refuses. The six restatements are converted to pointers instead, which is CLOUD-769's remedy applied consistently.CLOUD-774 — the gate that prices this punt measured the wrong instant
Filing CLOUD-770 and landing something else was the punt, and
filed-over-own-diff(CLOUD-514) exists to price exactly it. It did not fire, and the receipt says why:board-write-recordcomputed the intersection once, at creation, andfiled-here-checkread that frozen number. Rows are filed before any file is touched — AGENTS.md says claim by hand before writing code — so the compliant order and the evasion order are the same order, and it recorded0every time.The column now holds the paths a row names, which does not decay, and the intersection happens when the gate is asked.
board-diff-overlap --namedis the existing computation printed one line earlier; it needs onlygit ls-files, so a container with noorigin/mainrecords the row instead of losing it to-.Rows the PR closes are exempt, and without that this change would invert the gate. Recomputing against the landing diff fires on a row the branch filed and then fixed, whose paths are in the diff by construction — so every honest file-then-fix would need the override, and the cheapest way to dodge the refusal would become not filing at all.
closing-key-checkgains--listand is called, not copied: it owns$CLOSING_VERBS, and a second copy would be one value in two files with no gate holding them equal, which is the defect this PR is about.The nudge moves ahead of CI.
filed-here-check --advisoryruns the same predicate, pointer-only, exit 0 always, wired intostop-guardin last precedence — that file ranks by measured precision (3/3 vs 1/1) and this rule has none yet, so it does not take a slot it has not earned. It fires once per row per branch: a Stop hook cannot see a PR body, and repeating one pointer every turn is how the channel stops being read.§1b was specified and then dropped on measurement. Base-sha scoping cannot separate a branch reset from a rebase: after a merge the old base is still an ancestor of
HEAD, and "equals the current base" excludes rows filed before any ordinary rebase. A merge is that separation, solanddrops the branch's filing receipts where it already deletes the branch.Two
#MUTANTrows are re-aimed —overlap-ignores-the-diffhad become byte-for-byte the new mode — and a newoverlap-frozen-at-write-timerow is added, which only a case that files with an empty diff can catch.Corrections made during the work, recorded rather than quietly fixed
<root>/*.mdpathspec does not recurse, soworkflow/memories were never read. False — git pathspec*crosses/, and they were read. The claim came from reasoning about the glob rather than running it, in an issue about prose asserting what a mechanism does without checking. A bats case now makes the walk's depth a fact.ready-lintrejected CLOUD-769's first Ready block withbump-disagrees-with-type— it declared a patch wheredocsimplies no bump, and "no bump" is the one expectation that does not collapse to patch below0.1.0. The issue was corrected, not the gate.Verification
